Congratulations goes to DASBIS for the FTF on this one

To solve the numbers puzzle, place a number into each empty box so that each row across each column down and each small 9 – box square within the larger diagram (there are 9 of these) will contain every number from 1 through 9.  Or to make it simple, no number will appear more than once in any column, row or smaller 9 – box square.  Working with the numbers already placed in the puzzle, complete the puzzle with the missing numbers that will lead to the smiley.
